Yeast Nitrogen Base (YNB) media have been prepared according the formulae of Wickerham (1943-51) and Burkholder (1943). Their research on the nutritional requirements of yeast strains resulted in the formulation of YNB. YNB is a well defined composition of salts, vitamins, amino acids and a nitrogen source for a vigorous growth of Sacharomyces cerevisiae.
Y2035-01 is based upon the formulation of YNB except that all vitamins are omitted. The medium is used to test the requirement of essential vitamins.
Application: For carbon assimilation tests in the characterization and identification of yeasts.
